EVERETT P. RICHARDSON, OF LAWRENCE, MASSACHUSETTS.

,Letters Patent No. 102,159, dated April 19, 1870; antedated April 9, 1870.

IIPRGVEMBNT IN MACHINES FOR TRIMMING- THB HEELS OI' BOOTS AND SHOES.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern..-

Be it known that I, Evnentr'r P. RICHARDSON, of Lawrence. in the county of Essex and State of 'Massachusetts, have invented a new and useful Improvements in Machines f'or Trimming the Heels of Boots and Shoes;v and I do hereby declare vthe following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings forming' a part of this specification.

My invention has for its object the trimming or shaping of the heels of boots and shoes, in a more smooth, uniform, and expeditions manner than is done by the method now in use.

It consists of a knife or shave, of the curvature desired inl the heel, having iu addition to it's forward vcutting action a motion crosswise thereto, to produce a drawing cut, which is so advantageous in cutting Heretofore, in machines for this purpose, provided with a knife of this class, having` ashaving mot-ion around the h eel, the knife has had a simple forward motion in relation thereto, and, if' not perfectly-sharp, met with much resistance, and was not easily governed, being liable to dig in or run out, and, even when sharp, not leaving the heel sufiiciently smooth.

My invention consists also in means for present-ing the heel to the knife in a proper manner.

A is the frame or standard.

B, a shaft, operated by the pulley C.

Upon this shaft is mounted the annular knife'D. which is made to out bythe rotation of the heel, the knife at the same time having a lateral or rotary mo-v tion in a direction parallel, or, nearly so, with its cutting-edge, thus giving a drawing cut. This motion may be reciprocating instead of a Arotary motion, and the knife need not be continuous, but may be any portion of a circle, provided it is somewhat more in length than the vheight-of the heel, while, in some cases, a straight knife might be used.

The heel, as isA usual in hand'wo'rk, has its toplift b cut out by dies, to the form, and near the size desired in the finished heel, and, being driven on'in the usual manner, governs the shape and size of the heel, by being held against the gauge or guide E, which is so adjusted that the knife slightly trims the said top piece or top lift, while cutting the more projecting portions of the heels.

The heel is held up to the knife bythe action of the weighted frame F, operating asa level', having its fulcrum at c, andis retracted by the treadle G through knife forms the upper portion of the heel independent of the gauge E.

The form of this portion of the heel may be deter mined, and made to conform to the shape of' the upper, by the shoe being'held up to a suitable guide, resting against the counter f, orthe operator may conf trol it by the handle I.

The clamping-of the shoe is efiected'by the handle I being pushed toward the shoe till the pin g is liberated from the slot h in the'sleeve t; the handle I then being turned, its inner end is forced up to the shoe or last by the inclined end of the sleeve i.

Heels.m ay be shaped by this machine before it is attached to the boot or shoe, when desirable.

The invention is also applicable to the trimming of the edges of boots and shoes, if somewhat modified in the devices-for holding and moving the work in relation to the knife.v

What'I claim as new, and desire to secure by Letters Patent, is-

' 1. The knife or shave D, having, in addition to its forward shaving action around the heel,- a motion crossv wise or laterally thereto, for the purpose of effecting a drawing cut, substantially as described.-

2. The annular knife D, in combination with the devices, substantiallyas described, for moving and guiding the heel in relation thereto.

3. The pivoted frame F, in combination with the clamp H, substantially as and for the purpose set forth.

4. The gauge orguide E, so arranged as to rest against the edge of the top lift of the heel, Substantially as and for the purpose set forth.'

EVERETT P. RICHARDSON.
